2. The World's Fastest Runners: Slowed Down & Up Close
Take a close look at the the fastest man in the world and other runners as they sprint 100 meters. Observe how their muscles, breathing patterns and even facial expressions are all related as they race toward the finish line. This displays how intricate our body systems are and how they work together to perform different body functions.

Add the new notes to your table of contents, and then turn to the next clean page and set up your title and date

6. Levels of Organization
Recall that there are 6 characteristics of living things, we are focusing on two for Unit 5:
all living things are made up of cells
all living things are organized

8. Add tissue to your index
Tissues are groups of similar types of cells in multicellular organisms that work together to carry out specific tasks
Humans, like most other animals, have four main types of tissue: muscle, connective, nervous, and epithelial
Add tissue to your index

9. made up of layers of tightly packed cells that line the surfaces of the body
examples of epithelial tissue include the skin, the lining of the mouth and nose, and the lining of the digestive system
made up of many different types of cells that are all involved in supporting and binding other tissues of the body
examples include tendon, cartilage, and bone. Blood is also classified as a specialized connective tissue
made up of bands of cells that contract and allow movement
made up of nerve cells that sense stimuli and transmit signals
nervous tissue is found in nerves, the spinal cord, and the brain

10. Add organs and organ systems to your index
Organs are groups of different tissues working together to perform a particular job.
Organ systems are groups of different organs that work together to complete a series of tasks.
Add organs and organ systems to your index

11. Multicellular organisms usually have many organ systems that work together to carry out all the jobs needed for the survival of the organism.

13. Place this tape-in into your notebook and label each level of organization

15. Systems may interact with other systems
Systems may have subsystems and be part of larger complex systems

16. The Circulatory System
includes the heart, blood vessels and blood
transports oxygen, hormones and nutrients to the body’s cells
moves waste and carbon dioxide away from cells

17. The Excretory System includes the kidneys and bladder
removes water, salts, and waste products from blood and body
controls pH
controls water and salt balance

18. The Digestive System
includes the stomach, small intestine, and large intestine
digests foods
absorbs nutrients, minerals, vitamins, and water

19. The Respiratory System
includes the trachea, larynx, pharynx, and lungs
brings air to sites where gas exchange can occur between the blood and cells (around the body) or blood and air (in the lungs)

20. The Muscular System
includes cardiac (heart) muscle, skeletal muscle, smooth muscle, and tendons
involved in movement and heat production

21. The Nervous System includes the brain, spinal cord, and nerves
collects, transfers, and processes information

22. The Endocrine System includes all of the glands of the human body
produces hormones
regulates metabolism, growth and development, sleep and mood

23. Homeostasis
What is the first sign that you may be sick?

24. Homeostasis
The systems in your body work together to maintain homeostasis Homeostasis is the ability to maintain constant internal conditions when outside conditions change

25. System Interactions
Nutrients are processed when the digestive, muscular, and circulatory systems work together.
The respiratory, circulatory, muscular, and digestive systems work together and process oxygen and move wastes from the body.
The nervous system communicates with the muscular and skeletal systems and coordinates movement and responds to stimuli.
